SPECIFICATION forming part of Letters Patent No. 733,106, dated July 7,1903. Application led February 6, ,1903i Serial No. 142,138. (No model.)

To all whom it may concern: u k tubular stem e and secured to theWick-tube a Be it known that I, CHARLES E. WIRTH, a and coming atopposite sides of the pinion e.

citizen of the United States,residing at W'ater- Within the tubular stemc and extending bury, in the county of New Haven and State from end toend thereof is a shaft f,\on the 5 of Connecticut, have invented anImprove` inner end of which is secured a tooth f, while 5 5 ment inWick-Raisers,of which the following on the outer end of the said shaft fis a'nut isa specification. p f2. The tooth f in the position 3 is Myinvention relates to a wick-raiseres- 'adapted to contact with thesurface of the pecially adapted for Argand lamps, the same ,tube a, andwhen the shaft f is given a half- Io'having an adjustable function-thatis, the `revolution said tooth comes into `the'dotted 6o possibility ofarresting the upward movement position beneath and is again adapted toconof the wick at the desired or apredetermined `tact with or stopagainst the wick-tube a position, according to the height of theV flameThis movement indicatesand controls the exdesired, also adjusting theparts employed as tent of the rise and fall of the wick. The parts thewick burns, so as to keep the wick at the are so constructed that theshaft fis obliged to 6 5` proper height for a smokeless flame. `turnwith the tubular stem e because the nut In carrying out my invention andin comf2 on the screw threaded end of said shaft bination with arack-and-pinion structure for bears against the end of the tubular stem,`raising and lowering the wick I employ a de` .while the tooth f bears`against the other end 2o vice capable of arresting the movement of theof said tubular stem. Consequently when the 7o Tack-and-pinion device,especially with the nut is clamped in position the tubular stem upwardmovement of the Wick, and which de-` and the shaft turn together. viceis adjustable for regulating the extent To adjust the wick, the nut isloosened and `of this upward movement. k the tubular stem c turned` toelevate the My invention` is represented Vby several wick to a positionwhere the Haine may burn 75 forms, the details of which are hereinafterwithout smoking.

Thewick-raiser outer surface oi' the wick and the prongs comprises theperforated tubel d, having octhereof to engage the same. i This band his 95 casional inturned prongs at the respective provided with aninteriorly-threaded portion, ends;` the pinion c, meshing with a line ofperthrough which the screw-rod l0 passes, the forations of the tube d;the tubular stem e', lower end of said rod l0 passing through an and theknurled disk e2 on the end of said tubuaperture in the bracket 3. 5o larstem, there being brackets 2, receiving the I provide a casing t' ofsheet metal connected Ioo by screws 4 to the upper end of the oil-font,and upon a flat surface provided therefor and adjacent thereto theoil-,font is provided with a guide-tube 5. The screw-rod 10 passesthrough the guide-tube 5 'and through a sleeve 11 and'through arack-tube 9, the sleeve 11 being fixed to the screw-rod 10 and therack-tube 9 rectangular in. cross-section and passing through acorresponding opening in the case. Above said rack-tube, secured to thethreaded end of the rod 10, is a head 12. Within the case c' is a pinion6, meshing with the rack-tube 9. Said pinion is upon a stem 7, the freeIend of which is provided with a knurled disk S outside the case. Therotation of the pinion 6 by the knurled disk 8 moves the rack-tube 9,sleeve 11, head 12, and the screw-rod 10 down and up with a verticalmovement and with said movement lowering and raising the band h, prongedarms h, and the wick g, the sleeve 11 forming a stop for the upwardmovement in the position Fig. 5 and the head 12, coming against theexterior of the casing z', a stop for the downward movement of theparts.

The head 12, screwed upon the upper end of the rod 10, is free from therack-tube 9,`

there being a slight play, so that by turning the head 12 the screw-rodand sleeve 11 may be rotated, said rod turning in the interiorlythreadedhub portion ofA the band h to raise or lower the band, the pronged armsh', and the wick g and adjust the height ofthe wick with reference tothe position of the racktube 9, so as to bring the wick when fullyelevated at the proper height for a smokeless iiame, the wick whendepressed by the movement of said parts going sufficiently low withinthe wick-tube a/ to insure the llame going out.

I have shown and preferably employ a friction-spring 13 (see Fig. 5) inthe form ofa bent wire, the free ends of which grasp the stem 7; butthis device being old in the art forms no part of my invention.

In the form of my invention shown in Figs. 7 and 8, k represents thefont for the burning iiuid; c2, the central-draft tube; g, the wick; Z,aband surrounding the wick and secured thereto by a device like thepronged arms 71, Figs. 4 and 5, or by any equivalent structure, and m isa bracket engaging the band Z. tically-placed tube n, extending fromnear the base of the font up within the same and above the font, andwith an auxiliary tube n in the upper end of the font-concentric andsurrounding the upper end of the tube n. In the annular space betweenthe tubes n and n there is a tube o, secured at its lower end to thebracket m and normally extending above the upper ends of the tubes n n.The upper end of the tube o is closed except for an opening providingfor the threaded upper end of the screw rack-rod o", which passesthrough and substantially iills the tube n. A knob 14 is on the upperend of The font 7s is provided with a ver-V this screw rack-rod?n and asimilar knob on the lower end. r1`he rod r passes out of the lower endof the tube n and through a casing fi', similar to the casing z', (shownin Figs. 4 and 5,) but inverted in its position, said casing beingsecured to the lower portion of the font by screws 15. A stem 17 passesthrough this casing, and on one end thereof is a pinion 16, engaging therack-teeth of the rod r I and on the other and outer end a knurled disk18, by the turning of which with said stem and pinion the screw rack-rodr is raised and lowered. s is a nut adjustable longitudinally upon thescrew-rod r.

'Ihe position of the parts Figs. 7 and 8 represents the extreme upwardmovement in which the nut s comes against the lower end of the casingfr" and in which position the wick is supposed to be at the properheight for a smokeless iiame. With the movement of the parts and thedescent of the rod a" the wick is lowered, and the limit of the downwardmovement is determined by the inner upper end of the tube o comingagainst the fixed upper end of the tube fn. As the wick burns and itbecomes necessary to increase the height of the same the nut s isrotated on the rod r and lowered. This when the parts are returned tothe position Figs. 7 and 8 permits the wick to be raised to the formerheight and to the required or proper height for producing a smokelessiiame.

The several forms of my invention illustrated embrace a device capableof arresting the movement of the rack-and-pinion device, so as toregulate the opposite movements of the wick, and also a device having anadjustable feature for regulating the extent of the upward movement ofthe wick.

I claim as my invention- 1. In a wick-raiser the combination with a rackand pinion; of a device coacting therewith and adjustable so as to bringthe wick to the desired or predetermined position according to theheight of the flame required, the adjustable function beingperformedwhen the rack-and-pinion device are at an extreme of theirlmovement.

2. In a wick-raiser, the combination with a rack and pinion, of a partpassing through a part thereof and having a regulatable function, andassociated means for limiting the upward and downward movement of thewick.

3. In a wick-raiser, the combination with a rack and pinion, of avertically-movable screwrod, a part connected thereto and movabletherewith and adapted to engage the wick so that the wick is caused torise and fall with the vertical movement of said screw-rod, and meansassociated therewith for limiting the extremes of this movement inopposite directions.
